Former England bowler Broad stated Australia are fielding the "worst" squad since 2010 ahead of the upcoming Ashes.
The bowler's remarks came in response to predictions from ex-Australia batsman Warner suggesting the English might be defeated the series in Australia 4-0.
England's last triumph in Australia occurred in 2010-2011, where the bowler was part of the team which won by three matches to one keeping the Ashes trophy.
Nevertheless, they have suffered comprehensive defeats including whitewashes and clean sweeps during three trips to Australia after that.
"It's extremely challenging to win on Australian territory as an England side, or any side - that's the reality," Broad commented.
"The hosts have to be massive frontrunners. The question really was 'Who is facing greater expectations?' Well, the Australian side face significant expectations since they're expected to win. They are exceptional on home soil."
"But they've got uncertainties regarding their team and doubts about [the fitness of] captain [Pat Cummins]."
Broad retired from professional cricket after the Test series on English soil in 2023, when Australia kept the trophy with a tied series.
He continued: "You wouldn't be outlandish in thinking - it's actually not just a view, it's factual - it's probably the weakest Australian squad since 2010 where the English last won, and this represents the strongest English squad after 2010."
"Therefore these factors align to the fact it's going to be an exciting Test contest."
The first Test begins at the Perth stadium on 21 November, and Australia's preparations have been hit due to the possible unavailability of skipper Cummins, and he has not played for months due to lumbar bone stress affecting his spine.
The pace bowler is still recovering from the problem stating he's "less likely than likely" to feature in the first Test.
His absence could leave Australia with a bowling attack of Starc, Josh Hazlewood plus Boland, all of whom are in their mid-30s, with their other seamers inexperienced and unproven in international cricket.
The packed Ashes schedule - five matches in seven weeks - ensures each team will be tested by injuries.
"The Australian team were so consistent over many years so that you just knew who would open the batting, who was going to bat in which position, what bowlers there were - and they don't have that," commented Broad.
"It's quite comparable to 2010-2011 when the English triumphed there."
"The reality is Australia generally have to be bad to lose in Australia and England need to be very good."
"The English team are well positioned to be outstanding and the Australians could potentially end up bad."
"I don't think any observer could argue that this is Australia's least strong squad in over a decade... it's just a fact."
