Elsa the koala, the joey who captured media attention in October when Australian Reptile Park staff stepped in as surrogate parents after her mother stopped producing milk, has started pre-school.

The cute little ball of fur named after the Disney queen is now 10 months old, no longer needs milk and is happily sustaining herself on eucalyptus leaves.

The next step in her recovery was to introduce her to other joeys her age in a "koala pre-school" at the Central Coast park.

Koala expert Hayley Shute, Elsa's surrogate mum during her infancy, was understandably anxious about her little girl mixing with the other kids.

"As a mother myself, this was no different than sending your kids off to their first day of big school," she says.

"I was very emotional at first as she's been by my side for literally months now, and it's a big change not having her around."

But Hayley says Elsa has settled in "perfectly" with the six other joeys what were part of the park's 2019 breeding season.

Hayley has some skin in the game after feeding Elsa specially formulated milk every five hours, including at 2am, and ensuring she was in sight at all times as joeys stress if they can't see their mum.

Koala numbers had plummeted to an estimated 85,000 last year before the recent bushfires wiped out perhaps a third of the NSW population and maybe half the 50,000 chlamydia-free koalas on Kangaroo Island.

Speaking of which, Aussie PR company Cummins&Partners has been hanging stuffed toy koalas around New York landmarks, including Washington Square and the Brooklyn Bridge, to attract people to a fundraising campaign in aid of the WIRES wildlife rescue group.

The toys come with a barcode directing people to Koalas of NYC GoFundMe page.

Self-confessed league "massive jersey nerd" Steve Russo has uncovered an interesting image from the Knights' premiership-winning season in 1997.

Russo, a former journo at Rugby League Week who now works for Kayo Sports, posted a screen grab on Twitter showing Matthew Johns and teammate Lee Jackson shaking hands with Roosters players after a game at what looks like the Sydney Football Stadium (RIP).

Johns appears to be wearing a 1996 Knights jersey, notable for its slightly different "RL" logo, while the English hooker is wearing the correct 1997 kit.

The controversy may not be enough to see the club stripped of its maiden title, but it does raise the question why Steve was trolling that closely through footage from 1997.

Too much free time?

If anyone can shed light on the jersey scandal, let us know.
