Where can I get a lockable tray (not canopy) suitable for Outbacking?

Any tray builder would be able to make that up. Just let your fingers do the walking.

Have a look at JohnR's GU Ute. He has a similar setup.

Hi Gareth,
As truckster said mate....heaps of them in yellow pages. One word of advice though, dont cut back on the thickness of the sheet metal. Off roading will cause cracks if too thin. I just had some tool boxes specially made for my trailer. Had them dust sealed and all. Now its a pleasure to toss my stuff in them and take off. rather than spend hours trying to figure out where to put it all without damaging anything.
Good luck with it.

Gareth,
if you are in Sydney go see a company called brightweld, thay are at Kings park nsw ph 9676 7719 they do a lot of this type of work, the company i work for has just got three service bodies built by them all out of 3mm thick aluminium they can even make them remote keyless entry if you like and best of all you can have as much input to the design as you like. There web page is www.brightweld.com.au and there is a picture of a duel cab rodeo done with a similar back to the one you are looking for. We got ours done in mill finish but the checker plate would hide all the scratches.
hope this helps

I would try the Car yards that have traded in a vehical with one on it they will probaly swap for your tray as they can sell a ute with astandard tray quicker than one with a custom tray worth a try any way,
Have a guy in town here that wants to swap his but it is in West aust.

G'day Gareth,
I am just completing the "truck pod" which will form the other part to the new outback hardfloor camper also nearing completion.
I am in Melbourne, don't know where you are, but I should have both prototypes completed by the end of the year and available for inspection.
The truck pod is a self contained unit that is designed to lift on and off the trayback as and when required. It is all aluminium frame and chequerplate aluminium panels and doors. The first one has a 120 litre stainless fridge freezer built into the pod. We intend to market models of the camper and the truck pod with or without our own brand fridges built in.
If you are interested I can give you further details of either the hard floor camper or the truck pod or both, via email.
They won't be cheap but they are rugged and are built to withstand the outback, ie. built for a purpose not a price!
Hope this helps,
Murray
