So here we go again, I can't put a link up from my WA morning paper as I am not an online subscriber!
I know if I take a photo from paper and put it up here that you lot don't like that either, so I will hand copy verbatim a condensed version, along with reporters names!

Contact tracers are racing to identify anyone who may have been exposed to three truck drivers who tested positive to Covid-19 after spending time I'm WA last week.
Genomic sequencing on Wednesday expected to reveal whether the cases were Delta, or the more transmissible Omicron variant.
Two fully vaccinated truck drivers in their 30's entered WA together from SA in the early hours of Thursday December 9th. They returned a negative PCR test before arrival and undertook a rapid antigen test at the border, which also came back negative.
They spent 3 days in WA before returning to SA on Saturday December 11th while on route to NSW.
They were swabbed again on Sunday and on Tuesday, SA health authorities informed their counterparts in WA that both drivers had tested positive to Covid-19.
So it is possible both men were infectious during their 3 days in Western Australia Health Minister Roger Cooke said.

So we haven't even opened our borders yet and fully vaccinated drivers are bringing the Covid-19 virus across our border?
What's going to happen when we do open up?....I just don't think we can stop the spread here in WA once our borders open for good, if these both pre-tested and fully vaccinated people entered WA and walked around Perth visiting multi venues then we here are goners!
