Q. So I am building an underwater ROV and my team needs a camera to mount onto our robot. It needs to be water proof, but if you have to buy a separate box it might be okay. It should be wireless, but we could run a Ethernet cable if we have to. And of course it needs to be able to live stream onto a laptop on the surface of the water.
I have looked into using a Go Pro, but I am unsure of what model to get and Go Pros seem a little pricey, so cheaper options may be better.
Does anyone have any ideas on what i can use? If i use a Go Pro i need to know which model is best, but I would like cheaper options if they exist. Thank You

A. Underwater wifi is relatively new and not "readily" available.

at least, not from regular stores. If you are depending on the GoPro wireless connectivity to do what you want, I would bet against it - at least for now. That means some sort of tethered version. As far as I know, there is no wired, direct, "streaming" capability that will do what you want. Remember, the GoPro is a camera/camcorder and designed to capture video locally to a memory card.
Wireless communication is one thing - wireless video is a whole different animal (bandwidth issues in the aquatic/marine environment).
And if you are using a robotic craft, I am guessing the ROV is going to be more than 100 feet away which means if on land, would be on the edge of wifi's reach - underwater, even more so. The GoPros included waterproof housing is rated to only 40 meters (~130 feet).
A camera-only (no local recording), with a cable, solution may be a more do-able option. Since we don't know how deep the camera needs to go and we don't know how far away the camera will be (it could be 5 feet deep but 300 feet away) it is impossible to actually make a recommendation. This shallow, but far away is different than 300 feet deep because of the pressure exerted at that depth.
Your solution may be as simple as

which is even more than the GoPro. This is an underwater wired camera designed to do what you want. Similar to a security camera, it has a single cable that includes connections for power and the video feed. The power is supplied on the computer side of the cable - the camera does not carry local power. The camera does not store video locally, but sends the video over the wire to an analog/digital converter. This can be a standalone box like those from Blackmagic Design, Roxio, Elgato, Thompson/Grass Valley/Canopus or a card fitted to the computer.
And keep in mind that at about 40ft-50ft and deeper, you will likely need to add light. Underwater lighting can be pricey...

Where can you get cheap polaroid cameras in australia?
Q. Does anyone know?
A. Why do you want 1950's technology?. Polaroids stink, I sold this cameras when they were first introduced and it went like this: Sell 3 cameras and two are returned. The third is/was up in the attic just waiting for gullible people to come along and think Polaroid instant print is the cat's meow. Well I guess 2013 is the year of gullible people. PLEASE don't waste your money! Two dollars a print equals 16 dollars expensive. BUT what if all 8 prints do not come out? The entire 8 prints never came out when I sold the cameras. I can't figure where all the Polaroid cameras are coming from. Polaroid must have stock piled them and then sold them this year. Stick to regular 4x6 prints priced at (here in the USA) from 13 cents to 20 cents a piece. Plus your can get reprints from the digtal file. Never mind that Polaroid prints fade in a few years while digital prints last a least one lifetime, more if stored in an album. Please don't buy.
