The All Blacks have dominated the annual tournament, which is usually played over three matches, as they have emerged victorious in every year since 2002, while last year's success was their 46th overall, while the Wallabies have emerged victorious on just 12 occasions.
However, Australia did win the final match of the 2017 series, claiming a 23-18 success in Brisbane last October, and Haylett-Petty insists 'confidence is building' within Michael Cheika's squad.
"We feel like we are getting closer each and every year, and the confidence is building,' Haylett-Petty said. 'We feel ready for this year. There's a huge hunger."
The Rebels star has certainly been impressed by the quality within the Wallabies squad and he is convinced, regardless of the results they end up picking up this year, they are heading in the right direction.
He added: "From inside the camp when you're training together and you see some of the quality within our group, there's a lot of belief there that we're heading in the right direction."
The opening two matches of this year's Bledisloe Cup will once again form part of the Rugby Championship, while the final game will be contested in Japan at the end of October.
