The spring show of the Porongurup Range

The spring show of the Porongurup Range

South-western Australia comes alive with colourful flowers in spring – the Noongar seasons of Djilba and Kambarang. There’s a beautiful wildflower display in the Porongurup Ranges, particularly in the months of September and October. 

Wattle wonders

Following record rainfall in 2021, local native wattles were bursting with colour in September and October around the Porongurup.
