*** UPDATE ***
Alright, I've heard you guys loud and clear. I am a hopeless idiot probably living off backdoor rub-and-tubs whilst smoking ice in the streets next to the garbage bins. I've finally learnt my lesson and I'll be sure not to repeat it again. However, I've searched the bloke's number online and turns out he's a serial scammer. I don't want to risk suspension or ban by posting specifics but he has been scamming for at least 3 years now. His real name has been out and about and three supposed addresses (all within Victoria and coincidentally, 35 ~ minute driving distance to South Bank) has been linked with him. Apparently he's even been imprisoned for 20 months but is now out on parole or have been released. Obviously, that all should be taken with a grain of salt (I could speak) but this information has been repeated by multiple people on multiple websites over multiple months. Some have apparently reported this to ACORN and Victoria Police, but he's clearly still operating, whether it's him himself or an accomplice or two.
I believe I have his current bank details - he has previously been with two others, and a phone number that he has been using for a while and clearly didn't think to change. This on top of his real name, addresses, etc that I've found.
Any further help would be appreciated - I do hope that I can at least help take down this bogan back to the hole he was born in.
