International representative rowing
Watts made his Australian representative debut in 2017. He rowed in the Australian eight at the World Rowing Cup II in Poznan and then in the coxless four at WRC III in Lucerne. For the 2017 World Rowing Championships in Sarasota, he rowed in the seven seat of the eight which missed the A final and achieved an overall eight place finish.
In 2018 he was in contention as Australia's single sculler and rowed that event at two World Rowing Cups in Europe finishing in C finals at both. The Australian quad of David Watts, Alexander Purnell, Caleb Antill and Luke Letcher also raced at two WRCs and then at for the 2018 World Rowing Championships Letcher was changed out for Campbell Watts. With Watts in the two seat, that crew placed third in their heat and then in the repechage went out hard and alongside New Zealand they surprised the Lithuanian world champions knocking them out of the final. In the final the Australian quad rowed through most of the field from the 1000m mark and finished in second place to Italy for a silver world championship medal.
On the back of his 2019 Australian national championship win in the double scull he was selected with Hamish Playfair to row Australia's double scull for the 2019 international season. They placed 5th at the World Rowing Cup II in Poznan and 6th at WRC III in Rotterdam.
