Hey man, I know this is way over your budget but I'm throwing this out here if you're in a serious pinch. I live on the Mornington Peninsula in Victoria. I've been doing the math and the whole trip is looking to cost around 1.3k for van hire, fuel and freelancer cut. I'm 18, have my p's am allowed to drive vans. So if you need someone to do the trip desperately, and you have the lifting equipment on you, message me back. I'll leave today, get to you sometime towards this evening/night and look to have the cargo in SA by tomorrow evening. Totally up to you though but I just thought I'd throw out an olive branch here, just in case, if you're interested. Let me know so I can get a van sorted for you in the morning :).
