Hello,
I am an Australian, based in Melbourne. I am looking for any other aussies that could lend me either BTC or USDT for four weeks.
PM me if interested or contact via Telegram.
Without collateral, there is no chance to get a single satoshi from anyone. The only thing that you can get is some negatives for asking for an uncollateralized loan.
By the way, why does the lender have to be from Australia? This won't change anything.
