ID Help?

[thelonehipster]

Was wondering if anybody could help me identify this species I managed to snap a good picture of today in Katoomba NSW. Lived here for many years and only in the last few have I seen these guys


Best photo I've been able to get the numerous times I've spotted these guys. When they want to run they're very quick
