Aqua Systems' backpack sprayer is currently half the price of other 15L sprayers, spotted in the latest Bunnings Catalogue. Verified in VIC and NSW, probably also on sale in other states as well.
While this is designed for weed-spraying, a backpack sprayer is a handy tool if you are defending your house from the bushfires this season:
Allows you to carry 15L of water with minimal strain, and it allows you put out small spot fires quickly, using only a tiny amount of water per spot fire.
15L of water goes a hell of a long way when you are using this backpack
Stay safe, and follow the alerts.
