The Adelaide Superdrome proved fertile home town ground for South Australia claiming four of the seven titles on offer.
Anna Meares won her 34th national track title in the women's team sprint with Steph Morton.
“I’m trying to keep ahead of my age. It always means a lot to me. I have been in some big competitions over a long period of time but National Championships, on a home track with a home crowd, always hold a special place in my heart," said Meares.
In the men's team sprint, Matthew Glaetzer partnered with youngsters Jai Angsuthasawit and Patrick Constable for the win.
“In an Olympic year, for me, I treat every race, every training as a rehearsal for the Olympics – it’s practice to make sure you get everything right," said Glaetzer.
Alex Edmondson, Miles Scotson, Alex Porter and Callum Scotson raced to South Australia's seventh straight title in a National Championship time.
“Every time you come to a National Championship you always want to go well, I wanted to get my sixth straight title, I am happy to do that with these guys,” said Edmondson.
Danielle McKinnirey, Alex Manly, Chloe Moran and Maeve Moroney-Plouffe clinched the women's pursuit title, closing out South Australia's dominant day on the boards.
"It was exciting the last two years I have done in the elite and we have come second and third so it is good to get up there on the next step and take the title," said McKinnirey.
In the under 19 events, Victoria and NSW claimed the women's and men's team sprint event, while Jade Haines took out the scratch race.
