Brisbane - oxygen for welding borrow please

Hey fellow brisbaners. I was wondering if anyone on here had an oxygen cyclinder I could borrow for a weekend. I’m almost finished my project and my oxygen ran out and I don’t want to buy another bottle from boc as I’m planning on handing my bottles back (and giving myself a break from the rental fee!) So can’t justify buying a new bottle. I’ve got plenty of acetaline if you need in return. Anyway, if anyone would help out that would be grand. Cheers
