As the meet came to an end Australia took home 13 medals - four gold, five silver and four bronze.

For 16-year-old Pallister, she re-wrote six of her personal bests, winning gold in the 400m, 800m and 1500m freestyle and silver in the 200m freestyle while also playing a key part of the silver-medal winning 4x100 and 4x200m freestyle relay teams.

She rounded off a successful Pan Pacs by shaving 20 seconds off her 1500m freestyle personal best (16:08.09) to set a new Championship record and make the top 10 Australian All-time record for 1500m.

Her performance saw her leapfrog her mum and 1988 Olympian Janelle Elford.

Elford, a two-time Olympic finalist, Commonwealth Games gold medallist and two-time Pan Pacs champion over 1500m freestyle, is now her coach and was with Lani poolside.

“I’m just so proud of her, as a mum and as a coach; she has worked so hard and she really deserves it, just a wonderful feeling...I'm happy for her," said Elford.

Pallister's gold in the 400m freestyle once again saw her surpassing her mum's personal best from Seoul 1988 with a time of 4:07.76.

She joins an exciting group of middle-distance freestylers which Australia hasn't seen since the late 1980s and 1990 when a young Hayley Lewis won five gold at the Auckland Commonwealth Games at just 15.

The current crop of young Aussies are being led by Australian and Commonwealth record holder Ariarne Titmus along with Pan Pacs teammates Kiah Melverton, Kareena Lee and Madeleine Gough.

It is less than two years to Tokyo, Pallister is in with a real chance to bring out the best in her Australian teammates and push for an Olympic team.
