This weekend marks the start of Webber's 12th season, and his seventh for Red Bull, and he begins it on home soil in Australia as the oldest man in F1 at the age of 36.
Unsurprisingly, it has led to suggestions - and not for the first time - that the forthcoming campaign could be his last, especially as Red Bull have him on a one-year rolling contract.
Webber, however, has been assured by team principal Christian Horner the deal will continue to be renewed as long as he maintains a high level of consistency, as has been the case the past few years.
Should there come a time when Red Bull opt not to renew, that is the day when Webber will likely turn his back on F1 and avoid the sort of situation faced by Rubens Barrichello.
After six years with Ferrari, Barrichello joined Honda, and during the 2007 and 2008 seasons, the Brazilian scrabbled around towards the back of the grid picking up the odd point here and there. He later drove for Brawn GP and Williams.
That is not something Webber plans on doing.
"For me to finish at Red Bull is quite likely," he said.
"But you never know, someone might ring tomorrow with something else. It's a funny old business, Formula One.
"But chopping and changing teams...I admire Rubens for that.
"I couldn't have done what he did in terms of being at the top and winning races and then going back down through teams in Formula One and being in an uncompetitive environment.
"That's something that would be quite difficult. I'm not particularly keen on doing that."
At least Horner's remarks are cause for optimism, with Webber adding: "It's a bit of a no brainer for the team as well as we've been very successful over the past few years.
"We've had our sticky periods here and there in terms of the drivers bumping into each other a little bit, in particular 2010, and certain other parts here and there in other years.
"But when you're getting the results you have been, and if that's the team's position, then it's obviously good to hear."
Despite his longevity, Webber is also old enough not to look over his shoulder and wonder as to whom might take his seat should Red Bull decide to look elsewhere.
"Kimi (Raikkonen) was close to replacing me in 2009," said Webber.
"When you're in a top team it comes with the territory.
"The vultures have been on the branches for the last three of four years. That's the way it is because there will be a day when I stop."
