just random thoughts....
Free drinks at the OX sounds about right usual bar staff country town wind down. Partiers (good lookin girls)in the cool circles are always welcome on the low down to these hours.
Janine having no money'purse it appears was keen to get the party started again. (I laugh out loud thinking about her at 31 still like this...on a work night!

my body stopped all nighters about 21

)
My gut can't shake the idea that it was somebody on the way to the OX free drinks post work so either someone knocked off from the tav or knocked off from the OX. Its not as likely a man would be welcome to free post work drinks unless he is a part of the work crew/scene......
and my other thought....Janine was simply way too cool for the churchy living in the boys home chemist. I just don't see her getting in his car no matter what he could have suggested.
Not when she is in the company of friends ....even irritated about the phone call I think she would have only jumped off for someone whom she was impressed with (hot/attractive?? or offering her entry to the party scene she heading too).
Another thing that bothers me is tied to the above thoughts....
Growing up in a town like Bathurst and visiting in my youth PLENTY of towns of equal status....closing times are the same are the same are the same......
.everywhere.
Post drinks with the bar staff is pretty well known.
It is totally possible a random stranger was in Bathurst maybe for work, over night passing through whatever who knows how closing time works....
Seeing Janine ready to keep the party going he could have had eyes for her all night at the tav.....bluffing his way to the next shindig?
Whom ever she gave her number to is key to her disappearance IMO.
That's my feelings about it after listening to the chemist episode.
