Yeah, You know - I already did the exam yesterday, there's only one panel physician and I didn't wanna upset them after i've set a date, lol. I can only hope it'll go faster than SlowerMy experience is similar with a long running PMV 300 (July 2018).
The request for the first Health check is automatic after submission
After that they are as requested. Sometimes the gap can be more than 12 months
August 2019 ours expired but it took until 30th December for the Police Check request - which I missed!
then in Jan 2020 they asked for both.
For medical you require a formal request at testing centre so don't waste money until asked.
For Police Check they should still be valid as it's only a record check but of course the day after you could go beserk!
Now with COVID we have just received the s56 requests for the processing of the Onshore grant of the PMV300
