An interesting question.
From my brief perusal of the web, anchors and testing pertain to workplaces.
Generally, strata schemes are not considered to be workplaces. ( yes people work from home in the building, and contractors work on the building, but under legislation, that does not class a strata building as a workplace).
Unless you have a building manager who can come up with the certificates, if I was a contractor I would consider the anchors uncertified and make my own safety arrangements.
I hope someone in the industry (and not a consultant trying to sell his services) can chime in and provide an answer.
