England beat depleted Diamonds 3-0
Australian coach Lisa Alexander says her English counterpart needs a reality check if she thinks the British team are right up there with the top two nations of world netball.
Alexander's comments came after England completed a three-Test series whitewash against the depleted Diamonds with a 58-51 victory in Birmingham on Saturday night.
She acknowledged the Brits under coach Anna Mayes were much closer to the No.1-ranked Australians and New Zealand.
"But I think Anna also has to have a reality check in terms of we've got seven starting players out of our line-up," Alexander told AAP.
"You've got to be a little bit circumspect.
"But certainly they are competitive and they're hungry and they want it - and that's something that's been missing from England for a little while."
Anderson said Australia had considered cancelling the tour because of the number of injuries to key players.
The team also lost captain Natalie von Bertouch before Sunday's first Test with a recurring finger injury.
"We might have seen a different result if we'd had Nat," the coach said.
The Diamonds started strongly on Saturday but the home side rallied and then overran the world champions in the second half to win by seven.
The attacking Sasha Corbin led the resurgence for England as the Diamonds' early precise passing went astray.
Mayes was delighted with her team's performance all week that included a 58-53 win in Bath and a 51-49 victory at Wembley.
"These guys have worked relentlessly - not just the last couple of weeks but the last 18 months," Mayes told Sky News after the final buzzer.
"They've been on the cusp of being able to pit our performance against the number one and two in the world and I think this belief is now instilled in them."
England are third in the world just ahead of Jamaica.
Anderson said the Australian players were devastated they hadn't been able to win on Australia Day but were remaining positive.
"They know they've got to learn and do things better," she said, adding it was great for youngsters such as Kim Ravaillion, Chanel Gomes and Saturday night Test debutant April Letton to get valuable court time.
The coach said the UK tour also proved the world champions needed to do more strength and conditioning work if they were to match England's toughness.
Rangy British defender Eboni Beckford-Chambers was named player of the series.
