The black and teals didn't have an open's side in 2018, then banded together a group of players that eventually went on to take out the Western Women's Rugby League top grade title 12 months on.

It was a stark turnaround, and the challenge now facing head coach Marty Lyden and his ever-evolving playing group is backing up that effort in 2020.

Can they go back-to-back? Lyden doesn't mince his words.

"Yes," the experienced mentor said following the Vipers' first training run on Sunday.

"We have just about the same squad as last year and a few new girls too, but I don't know a lot about the other teams at this stage.

"We'll be competitive and it'll be a good fun year. We've had a good turn up on one day's notice for our first run (on Sunday) and the girls are keen to learn. It should be good."

The Vipers will be without two key members of last year's grand final success in the form of Bec Ford and Lailee Phillips, but the strength of the club is without doubt its juniors.

The Vipers under 18s squad has long been one of the best in Western Division, and helping those young girls progress into the top grade will be a goal of Lyden's in 2020.

"It's still early on so the competition is in a development phase and getting the girls to experience rugby league is what it's all about," he said.

"Everyone wants to win, but it's more about giving the girls the chance to play."

The new WWRL premiership will be played over five weeks with a finals series, with the same six clubs set to field teams in all grades - open's, under 18s, under 16s and under 14s.

The only change is a change of identity for last year's Mudgee side. They'll be known as the Midwest Brumbies, joining the Vipers, Panorama, Castlereagh, Woodbridge and Goannas clubs.

Lyden knows his side will be the ones those clubs will be gunning for in the top grade, but given the improvement a lot of the Vipers' first year players showed in a short season last year, he's excited to see how some of his club's second year players develop in 2020.

The new WWRL premiership is set to kick-off in October.
