A match for the ages at the MCG saw The British & Irish Lions come from 18 points down to beat Australia 29-26.
Here are the key talking points…
Still all business
Enjoy the moment, but let's leave undefeated: Andy Farrell's message is clear – it is still all business for the British & Irish Lions.
Wrapping up the series in dramatic circumstances in Melbourne sparked predictable celebrations, but the real party can wait for Sydney.
You have to go back to the fabled 'Invincibles' of 1974 for the last time the Lions returned from an overseas tour unbeaten.
Farrell and Itoje have long been clear that winning this Qatar Airways Lions Men's Series has deeper significance.
Rugby participation, especially in younger age groups and in schools, worries the game's administrators. Farrell hopes the manner, drama and style of this win might just help change the narrative.
"The plan won't change, but we'll enjoy tonight as we've made a bit of history," he said. "If you're a child watching back home, you'd want to be a British & Irish Lion now."
Itoje delivers captain’s display
A big occasion calls for a big captain's performance, and we got that from Maro Itoje. He punched in tackle after tackle and bagged more turnovers than any other player.
Itoje's status as a Lions legend is now cemented: played two of three against New Zealand in 2017, started all three Tests in South Africa and won player of the series. And now this – a series-winning Lions skipper.
It was not just his stats that earned him the player of the match award, but his presence.
Even when the Lions were 18 points down, Itoje was calmness and coolness personified, urging his team to keep the faith with words and actions.
Wallabies a wounded animal
Andy Farrell warned his team to beware the wounded Wallabies after last week's win in Brisbane, and he was not wrong.
Joe Schmidt's team were a totally different outfit from the one beaten in Queensland, with returning forwards Rob Valetini and Will Skelton adding the physicality their coach had demanded.
Their bruising foundation showed just how good this team can be, with the old (James Slipper) and the new (Joseph-Aukuso Suaalii) both seizing their moments too.
When Valetini was withdrawn at half-time and Skelton seven minutes later, they lacked some punch but not spirit.
Back-rowers shine again
All the talk after Brisbane was about how Tadhg Beirne and Tom Curry had justified their selection as flankers – arguably the most debated call made by coach Andy Farrell.
Both shone again – and scored tries – and their fellow back-row, Jack Conan, was also immense.
The No.8 made 31 carries and 24 tackles in a remarkable display that embodied the Lions’ never-say-die spirit. A true warrior for the occasion.
Australia could ring changes
Joe Schmidt can take a lot of pride in the manner his team rebounded from Brisbane, and it is clear that Sydney – while not a series decider – is a chance to avenge.
Schmidt was smarting over the decision not to overturn Hugo Keenan's decisive late score, arguing Jac Morgan had infringed when clearing out Carlo Tizzano in the dying seconds.
He admitted the decision to withdraw Rob Valetini and Will Skelton after 40 and 47 minutes respectively was in the plan – the pair were decisive in establishing the Wallabies' momentum.
Harry Potter will miss next week's third Test with a hamstring injury, and the coach admits there could be others.
Schmidt said: "Potter won't be fit and there'll be a few walking wounded after a Test match of that intensity. We've a fair few bumps and bruises, so we'll have to see how they pull up."
