The organisation have claimed that the opening two domestic events of the year, both held in Brisbane, have shown the sport is entering an exciting era.

Swimming Australia chief executive Mark Anderson said high attendances and membership, record race entries and strong broadcasting ratings are positive signs for sport’s future nationally.

"The success of our two major domestic events in the first year of a new cycle following the tremendous success of our domestic events last year leading into Rio is extremely encouraging," he said.

"Swimming is entering an exciting era and it is encouraging to see continual growth across all areas.

"Right now, we have the high performance and grass roots areas of the sport being complemented by a united organisation working collaboratively with state associations and the wider industry.

"This is a fantastic position for the sport to be in as we open for submissions to host Swimming Australia events during the next four years."

Swimming Australia have claimed the revitalisation of the sport was evident due to the impressive broadcast ratings and attendance figures for the five-day Hancock Prospecting Australian Swimming Championships in April.

More than 2.9 million people reportedly watched the Championships on television, an event that also included the introduction of the legends relays and medal ceremony interviews.

At the venue, fans could watch poolside or head to the Centre Lane Precinct, which offered a range of gourmet food trucks, an arena pop-up-shop, Optus fan zone, entertainment and meet athletes or retired legends like Dawn Fraser and Ian Thorpe.

Attendance figures for the Championships were recorded at 12,000, while 230 children were able to attend swimming clinics with Olympians.

The Australian Age Championships were the largest in the event’s history with more than 1,850 competitors and 304 total clubs participating in the meet.

The Championships featured next generation of swimmers as they seek to begin their potential journeys to the 2020 Olympics in Tokyo, with coverage having been broadcast from the Brisbane Aquatic Centre live on Network Seven.
