Under Hamilton's captaincy, the Waratahs were undefeated through four round-robin games and has booked a spot in the grand final before the coronavirus pandemic forced the competition into shutdown before the finals series began.

It was hoped they would be played in late May, with the ACT Brumbies and Queensland Reds to battle it out to see who would join the Waratahs in the decider, but late Friday afternoon Rugby Australia confirmed those games would not go ahead.

As the minor premiers, the Waratahs were declared the Super W champions, extending NSW's remarkable record in the competition to three straight undefeated premierships.

"It's a bitter-sweet kind of thing, we won the minor premiership, so I think that's more what we are celebrating than winning a grand final," Hamiton said.

"It's a good place to be in given the current conditions even though it's not the ideal way to do it.

"It is a pretty special achievement, we have that mentality that we have to win and that also gives us confidence when we go into our games."

While Hamilton had participated in the Waratahs' previous campaigns and was a key member of the line-up, this season things were a little different.

The Australian skipper stepped into the shoes of former captain Ash Hewson following her retirement last year, and took the role with aplomb.

The number 8 finished in the competition's top five for defenders beaten, offloads and carries, while she relished the chance to foster the Waratahs' emerging talents as well.

The squad included a number of new faces such as Forbes' Lillyann Mason-Spice.

"It was exciting just to be given that opportunity and it was such a fresh group of girls," Hamilton said.

"It was such a nice environment, it's probably one of the best rugby environments I'd been in. There were people there that didn't let stuff get in their way, they were always fighting and giving 110 percent.

"That's the best thing about that generation coming through, that they are just going to give 110 percent to everything they do. It's so nice to see."

This season the Waratahs posted wins over the Melbourne Rebels (33-3), ACT Brumbies (41-8), fierce rivals the Queensland Reds (13-10) and RugbyWA (44-0).

But as impressive as that run was, Hamilton felt the Waratahs didn't produce their finest rugby, something she hoped the side could produce in the final.

"We hadn't played our best rugby yet this season, I don't think we'd gotten there, and that's why we were so excited to play in the final," she said.

"We wanted that to be our best game, we knew that we could make that better than any other game we played.

"Even though we were undefeated, we just weren't there, the best was yet to come for us I think. So we've just got to hold that kind of mentality going into next year now.

"So I really wanted to play, really disappointed that we don't get to finish. So for us as a Waratahs group we just have to focus on 2021 now."
