Those new versions of the hazard test are much better than they use to be, but what is on the vicroads is the style of graphics used today for the test. I did mine in December, and they looked like they did online. I personally haven't used the SA hazard tests, but I don't think it's the best idea.
The driving laws between states are somewhat different. Whilst it isn't a big change, it might confuse you a bit when trying to go for the read thing. So I don't think it's a great idea to use the SA test.
I don't have many tips for the hazard test, but if you've been driving for a while, it's really just a simulation to what you'd do in real life on the roads. As long as you can get a gauge for when to press the button, and know when to turn or merge into a lane, you'll do fine. Do the vicroads practice as many times as you like to feel comfortable. Good luck!
