IMO, the confusion in when Senior Constable Wendy Hudson first heard about a missing child that morning, is probably because some of her 2014 statement that was released at the inquest in 2019, was partly redacted.
You would think that if a child was missing, that word would get to someone like Senior Constable Wendy Hudson very quickly, even on her rostered day off (Saturday).
I can think of some very good reasons why what she might have then done soon after hearing that a child was missing whilst she was at the Tennis Club (not playing Tennis at a club she was heavily involved with for years, and probably frequently found at on a Saturday morning when not working), was possibly redacted.
I'm sure the rest of you Sleuths can too, if you were to put yourself in the shoes of a local cop in an area on their day off work, with a lot of known paedophiles (and probably a few maybe ones too), when a child goes missing.
I would be very surprised if the first Senior Constable Wendy Hudson heard of a missing child that morning, was as late as 12:20pm.
Whether she officially went back to work (as a Police Officer) at any point during that Saturday is an unknown at this point.
It's worth noting that Senior Constable Wendy Hudson took the Foster family to a nearby beach, a few days after William was alleged to have disappeared, whilst the search for William continued.

'In a statement, senior constable Wendy Hudson reveals details of the initial search for William and his foster family's reaction.
Ms Hudson said she took the family to a nearby beach, in plain clothes, while searchers continued to look for William on September 16.
Ms Hudson said she checked to make sure media helicopters were not following them, as they apparently sought a moment of peace at Diamond Head beach.
'We travelled a distance up the beach before stopping. We searched for shells with (William's sister),' Ms Hudson said.
'(The) male foster carer became upset and stood down near the water. I played in the sand with (William's sister) and we built a sand castle.
'Female foster carer joined us after spending some time with male foster carer, male foster carer then joined us placing a large stick into our sand castle.'''
