Citrus australis or the Australian Round Lime is native to QLD, from Beenleigh north. It is also called Gympie Lime, Doojay or Native Lime. It is a drought hardy native Citrus growing up to 5m in exposed locations or up to 10m in a forest situation.
The fruit have a thick rind and have a lot of oils present (they have been described as sticky golfballs). The flesh is good and sharp tasting. You can cut the fruit in half and squeeze the odd shaped vesicles out just like Finger Limes.
Citrus australis likes a full sun to part shade position with adequate moisture and regular fertiliser, just like normal Citrus. Easy to care for and drought hardy once established. Keep pruned to desired shape and height.
Spikes make this tree a Nest Plant for Small Birds such as the Superb Fairy Wren.
