Yeah, judging by the wording of those FAQ’s, I strongly assume that anyone who is actually checked and that cannot prove whether they are vaccinated or negative, will still be allowed into the groundThe LF part is worded as 'strongly encouraged' because ultimately you do not need to take a test if you've got a COVID Pass (Doubled Vaccination).
Also I've previously said, right now legally it's unenforceable to demand a pass as is merely a tool to help ensure high risk settings are as COVID safe as possible.
The club could make it mandatory as per their terms of entry but that isn't going to happen. Yet, to reduce the risk of hold-up, it's best to have one.
