Some transfer services are designed for larger amounts, and may have a minimum transfer amount as high as $5,000, while others would let you transfer one dollar if you wanted to. There’s no legal limit on the amount you can send out of Australia, although all international money transfers must be reported to AUSTRAC, and large amounts will be monitored. But some money transmitters may have a self-imposed transfer limit (e.g. $50,000 per person per day).
