Having coached in 2019 and being appointed for 2020, Mackay said it was exciting to be back.
“I'm really looking forward to the season,” he said.
“It was tough missing out on last year. The girls had worked so hard in the pre-season to build on what they produced in 2019 and to get better as a side, and it was such a shame to lose the season and all that hard work.
“I think a lot of our players will be desperate to get back out there.”
MacKay's side finished fifth on the ladder in 2019 but was eliminated by Echuca in the first semi-final.
Moama junior president Ben Hearn said MacKay had done a fantastic job with the club in his tenure, speaking highly of the culture he had built.
“He has had a brilliant influence on the development of the Moama youth girls program,” Hearn said.
“And he has ensured that enjoyment and inclusion are at the forefront of his coaching.”
While he expects most of his players to return and some new faces to make their debut, Mackay admits he had some concerns about what the year off could do to the women's game.
“For many it's still so new to them, so having a year off would have been tough,” MacKay said.
“I worry some players may have lost interest in the time off across the competition. I think that would really hurt the growth of the sport.
“But if that is the case, we will have a whole new group of players coming through for their first year who can become a part of the game.
“Women's football is growing so much, and I hope we see it continue to develop this season, and I really hope the year off doesn't hurt.
“I'd love to see all our players back for the season.”
