Thanks very much for the info, Blue. Those Grevillea are certainly beautiful and I always enjoy seeing them. There is another white-flowered species that is common on the dunes. They had already completed their flowering this year.
You will have lots of fun with Ctenotus in Perth! Plenty of species there to keep one amused for a long time.
Reptiles4me, the Marbled Velvet Geckos are faily common in the interior, especially up north. They are not hard to find.
