Wireless Hill has a little bit of everything and really shines in Spring when the wildflowers are out. The surrounding bush is home to many varieties of wildflowers, including orchids which flower between July and November, so it is the perfect place to go on a wildflower hunt. Wireless Hill Museum Perth Wireless Station, established in 1912, was one of Australia’s first links with radio technology and was used for telecommunications during World War One and World War Two.
