Hey everyone
Fairly new to boating - and novice at fishing, really impressed with the forum having lurked around for a bit, wanted to sign up hoping to reach out via the forums here in the hopes of finding some help / inspiration / guidance / company etc with regards to our family boat trips.
I used to hire tinnies a fair bit from Bribie marina for a number of years including the60hp plastic boat, until a few years ago where after 30+? years of procrastination, I went out and bought a “bargain” Sportsman Craft boat which was fun. After the rather steep learning curve that offered,  sold it to buy a Fraser Formula 626 as it was bit bigger, only to discover that learning curve kept goin'.
Usually hang around in Bribie Passage or near that bridge, not too far from the chip shop at the VMR . With the Fraser its easy going most conditions over to Morton even with a bit of chop. Prefer mid-week outings when there is no one around just maybe a mates boat. 
Have been thinking  of heading north to places like west side of Fraser and around  Hinchinbrook Island, and that inland bass fishing lake up there somewhere. Recently have had to put it up on tyres to get the trailer out as it looks a bit cactus, has some issues need sorting prior to doing any long road trips. and other adventures that am hoping we will have in it. Am sure will be great,  just need to sort a few things like the trailer and finding places to go that are away from the population areas. Thought it might be more fun hooking up with a few others doing the same.
Over the year’s friends have moved on or stopped going or lost touch - and shift work don't help either,  with recent global events just adding to it all.
Anyway that’s pretty much it, am hoping I can ask some not so clever questions and get this thing sorted. Looking forward to picking up a few ideas, learning a few things that may possibly impress the wife, and maybe make some new friends, possibly heading away on an adventure or two with the family without any major dramas (which probably would impress the wife)
Cheers

update on trailer situation
Have gone out and purchased a fairly decent 2017 dunbier rollered trailer at the correct length and with a healthy 2450kg rating, Has a decent electric hydraulic setup just need the vehicle controller. Should get us up and down the Qld coastline in safety for a while. Fyi, if your buying an unregistered trailer rated over a certain amount it will need a heavy vehicle inspection, this is where they measure it all up with a tape and do some other mysterious things and then your all good. Its free if you go to Pineapple St Zillmere Transport. So thats if its unregistered which this was.There main concern being modifications. Anyway all good now.
Thanks everyone for your thoughts.

They are being sold without warranty but either way, as it is the bracket that holds the brake calipers, you would think that they would not sell them as they are structurally unsafe. So just write them off as a tax loss deduction and just scrap them.
A few years ago I bought 2 complete axles from a well known local trailer component manufacturing company in the Brisbane area, when I did a checkup about 18mths later, I found water in the grease, so I pulled it apart and found that when they did the welding, they didn't put a sleeve over the bearing surface to protect it, so it ended up with the little ball bearing overspray on the area where the rubber seals sit, they didn't remove them and just pushed the rubber seals over it, greased it up and sold it that way without a care in the world.
Next issue was they didn't align up the caliper bracket correctly or used the wrong sized bracket before welding to the axle so the brake pads were hanging over the rotors outer edge by about 25%, so not achieving full braking capacity and wearing a big ridge in to the pads.
All I got out of them was "sorry" we will make sure it won't happen again, yeah right! That should not have happened the first time, what quality control?
Sad old state of the world where you have to check everything to make sure it is done right, that is what we pay them for. Lesson learned though! Now I check everything, and you would be surprised what I find making its way to be sold. 🤬

I purchased a Seatrail boat trailer for my 5mtr fiberglass boat (supposedly Chinese) but assembled locally. towed it from Wollongong to Port Hedland and back 5.5K each way, had no issues at all with trailer or towing. A lot of country roads in WA through the wheat belt

These guys are where I got my new trailer a year ago. Good solid trailer for the price. Imported I think but assembled in Brisbane.

Hey DanO, just be aware that those sold on E-Bay are probably made cheap, it would pay to go and see one in the flesh to see it's "quality" as well as its build before you lay down your hard earned cash. Once you start looking at 2T trailers it is more important to get a good build rather than a cheap build if you know what I mean.
I have seen plenty of trailers that are professionally made (and I use that term very loosely) which I would not be happy having them under one of my hulls. As the saying goes;  "you get what you pay for".
To give you an example here is an E-Bay listing for some axles, ignore the crud / dirt on the ends but just have a close look at the actual welds themselves and if that quality is anything to go by, then what is the rest of the trailers welds like?

Once you go over the 2000kg limit the price starts to climb significantly. You will need solid axles, as well as brakes on each axle including a breakaway  system as well, and yes, I would also go the 4mm SHS. As I said before, the steel component is probably the cheapest part. If you get it galvanized, that will also set you back quite a fair bit (probably $1500 plus) or you could start with galvanized SHS or I beam and then touch up with Galv paint, primer and more galv paint/epoxy, but you will not save too much due to the extra costs of the paints and extra time to coat it all so you will have to decide if it is worth going the slightly cheaper route.
That is the way I did mine but it will start to chip off after a while and you will not be able to get to the inner sections of the SHS,where the outside welding has burnt off the Zinc in the Heat Affected Zones (HAZ) on the inner SHS. Not to mention, it won't look as nice as a completely welded trailer that has gone to the Galvanizers. Some people completely seal off the SHS and then pour some oil into it. We made our comments based on a 5-5.5m boat, as yours is longer and heavier, then that is a different ball game.

He has a 5m boat so that one is way too big. A bit over 3K is what some of the the moderately priced one seem to go for new. I don't know how he arrived at 8-10K. 

I just used that one as an example just to show that a larger one would not cost as much as DanO was saying. Still it depends on how it's made too, as to whether or not he might need a larger size. Most of these on Ebay are really built to a price and he would need to take into consideration the weight rating it is made for as well, but just a replacement frame on it's own shouldn't cost him more than $1k  to build/replace.

I got my Sales trailer in 1999 for my 5.4m boat and it's still going strong. I did replace the axles, springs and discs once. It is one of the cheaper brands. I'd guess it would be a bit over 3K for an equivalent one now. 

Had a quick look on E-Bay and found this one, don't know if it is any good or not, but it  might suit you and it is certainly cheaper than the price you mentioned.

Over the years, I have built several trailers for my boats and even the 8m 3.5T only cost me about $5.5K, I only reused some of the existing trailers running rollers and arms, but that was about 6 years ago. Generally you can move the boat a bit on the trailer but you have to be aware that if you move it forward or back that it will affect the weight on the towball and also the steering at highway speeds as a result.
There is a maximum % distance that you are allowed from the axles to the back of what  it is carrying, been a while so have forgotten what it is now. If the lights are too far under the boat  it may cause you problems with the police and also the long overhang will cause the end of the boat to swing out too far when turning.
Most of the cost apart from labour is in the running gear ie; axles, tyres, breaking system, suspension, rollers, etc, so if you can reuse the existing stuff you would save a lot of cash, this is assuming that those bits are still OK to use and are suitable. The actual frame shouldn't cost too much to replace, after all, a few 8m lengths of Galv. RHS or equivalent,  plus primer and paint etc would be less than $1K, this is also assuming that you can weld properly and not using a cheap  Bunnings or equivalent home handyman welder with a 10-15% duty cycle running off a 10A power supply.

You can move the winch post forward if there is room. A bit of overhang is OK but not that much. 8 to 10 K seems high for a 5M trailer (that's about what my whole rig is worth which is a 5.4M boat). If you are in Sydney have a look at Sales Trailers which are reasonably priced.  

thanks everyone
much appreciated, 
cheers

Welcome to the AFO.
@GregOug is a member who likes to hit up the Northern Bay during the week. Myself and a few others also like to fish during the week, but usually stick to the Southern Bay. Although I do hit up East of Bribie occasionally when the weather is good, in my 4.7m runabout.
Hopefully you can get some answers and results from the forum.

hey Dano,
Welcome to the forum. Nice boat mate. 

Welcome to the forum.
There are no silly questions nobody's born an expert,
ask away.
