This hoya is a vine found on rain forest margins and rocky areas, and occurs in Indonesia, Australia (Eastern and northern Australia, from the Northern Territory though coastal Queensland from Cape York to northern New South Wales), Fiji, New Caledonia, Papua New Guinea, Solomon Islands, Samoa, Tonga, Vanuatu. It is a popular garden plant, noted for its fragrant wax-like white flowers and its ability to attract butterflies. Hoya australis prefers bright light, but will tolerate much less. Though it will tolerate low temperatures (but not freezing), the optimal temperature is 16–29°C. It benefits from an open potting medium that allows some air to get to the roots. Typical mixes include large-grade drainage material such as perlite, pumice, or bark balls. The plants should be fed regularly with Flowering Orchid Tucker from early spring and then Growing Orchid Tucker when finished flowering. Moderate your watering regime in accordance to your temperatures i.e. weekly in summer to every two weeks in winter. If in doubt, err on the side of under-watering. It has a cluster of white star-like flowers that are heavily scented and produce a sugary nectar. Rooted cuttings should take about 2-3 years to reach flowering size.
