Despite missing the first three rounds due to a date clash with Formula 4, Brown would go on to secure P2 in the 2016 championship, with multiple wins and podiums.

[6] Brown was named as a Supercars Endurance Cup co-driver, partnering Anton de Pasquale with Erebus Motorsport, where he immediately showed his elite driving ability throughout the 3 race series.

He continued to make solid progress in his Dunlop Super2 Series landing P6 in the 2018 Driver's Championship with Eggleston Motorsport.

Again partnering with Anton de Pasquale at Erebus Motorsport in the Supercars championship, Brown's talent was on show finishing P2 behind Craig Lowndes and ahead of Garth Tander in the Co-driver Race, taking his first podium in the series.

Brown began 2020 with a multi year signing with Erebus Motorsport (Penrite Racing), that would see him compete in the Supercars series as a co-driver to David Reynolds in 2020, before becoming a full time driver for the team from 2021.

The Supercars Enduro Cup was reduced to a single race at Bathurst for 2020, where Brown and Reynolds finished P15 due to engine issues.

He is the first rookie driver to win a Supercars race since 2013, when Scott McLaughlin and Chaz Mostert both took victories in their first full-time season.

In August, Will Brown announced his departure from Erebus to join Triple Eight, replacing the NASCAR bound Shane van Gisbergen.

[9][10][11][12][13] Brown started 24th and was in the top 20 at one point in the race before electrical issues relegated him to a 31st place finish three laps down.
