The first Grand Prix start for any driver should be a special occasion, but British rookie George Russell viewed his debut in Melbourne as more of a test session after a tough winter for Williams.

Delays with their car build saw Williams miss over a quarter of pre-season testing, with their running limited by a lack of spare parts. That has resulted in an uncompetitive start to the season, with Russell their lead driver in Albert Park qualifying - but 1.3 seconds adrift of the next slowest car on Saturday.

After then completing his first race in F1 two laps down on the leaders in 16th place, the 2018 Formula 2 champion says he was treating Australia like an extended testing session.

“From a personal perspective, you’ve only got your team mate to compare against,” said Russell. “Obviously I’m not disappointed to come out on top, but at the end of the day, I’m not interested in fighting him for last. We need to work to make this right.

Kubica rues 'complicated' F1 return after sustaining start damage

“Personally I can take a bit of satisfaction from this weekend. I think [Saturday] was a really great day for me. I left the circuit with my head held high. [In the race] we knew what we were in for. It wasn’t a fair fight with Robert [Kubica] as he had a bit of damage at the start. For both of us, it was just bring the car home and learn as much as we can.

“We’ve just got to treat these as test sessions because we’re so far behind, and we’ve just got to understand it and almost try things to see what works and see what doesn’t, because for now it doesn’t really make much sense to try and optimise everything when we are that far off the pace.”
