Zendesk (Melbourne) did layoffs last year, but this was small scale I think, and mostly driven by their company-specific troubles.
Some American companies like Google and twitter layed off etc. "Mark43, a US company that builds online platforms for public safety organisations like police, fire or other emergency services, made its entire Australian office redundant at the end of June. Former staff member Gary* estimates around 70 people were laid off, with most of them based in Sydney."
but also local companies

I'm a Tech Lead with a solid CV looking for a new gig. I'm finding it noticeably more difficult to get recruiter attention (let alone interviews) than I'd expected.
My gut feeling is that there are likely more candidates applying for any given job than there were late last year.
