Flowering Grass Tree

Busy bees and other insect are swarming these flowering stalks of this grass tree in Yanchep National Park last Saturday. The prickly 'leaves' keep me on a distance when I want to take a sniff to satisfy my curiosity if the flowers smell nice. So I still don't know... I've attached this photo of me standing next to the grass tree in the prickly scrub so the proportions of this plant are clear. And this is an average size, not that big yet. There are far bigger examples available, but not blooming as beautiful as this one.
