Lucas Browne has become Australia's first heavyweight world champion after an upset win over Raslan Chagaev

Lucas Browne had barely done up the buckles on his shiny new WBA heavyweight belt when a challenge was issued from across the Tasman, with Joseph Parker's camp saying they would be happy to 'humiliate' the Australian at the first opportunity

Browne, a tattooed, powerhouse slugger from Perth who trains in Sydney, earned a slice of history over the weekend when he stopped Russia's Ruslan Chagaev in 10 rounds to become the first Australian to hold a major heavyweight belt.

Due to the complexities of a muddled boxing hierarchy, he has become the regular champion of the WBA, which also boasts an interim champion in Luis Ortiz and a 'super champion' in Tyson Fury, who sits on top of the unified tree after his upset of former divisional overlord Wladimir Klitschko.

FIONA GOODALL Kiwi sensation Joseph Parker is rated as one of the most exciting heavyweight prospects in the world.

Fury is the man Browne craves a meeting with the most but he will have some bridges to cross before that eventuates. The 36-year-old would dearly love to defend the title on home soil and stands to take on Puerto Rican Fres Oquendo as his first assignment.

A far sexier local option would be to square off with Kiwi sensation Joseph Parker, rated along with Brit Anthony Joshua as among the most exciting heavyweight prospects in the world.

Parker, just 24, has a date with Carlos Takam (likely to be in May) that could put him one win away from a mandatory IBF title showdown with the winner of the bout between Joshua and American Charles Martin (April 9 in London).

But his management team made it clear they would love nothing better than to venture across the ditch to clean up Browne in what would be a lucrative and high-profile bout closer to home.

"We will unleash Joseph Parker onto Lucas Browne any time he's ready. We've never shied away from trying to make it happen over the last couple of years and offered substantial six figure purses in a bid to try and lure Lucas into the ring," said Duco's Craig Stanaway.

"However, Lucas has proved he has no intention of accepting the challenge against Joe any time soon. The reality is that Joe's got boxers across the globe nervous with just how fast his hands are.

"The boxing world knows that if Lucas and Joe were ever to meet, your Aussie champ would be humiliated and he'd be humiliated by a Kiwi."

They are legitimate fighting words and any bout between the pair would captivate fight fans from both nations, particularly in New Zealand where Parker has become a top-shelf celebrity as he wades through opponents in fine style.

It would represent a stern test for the youngster, who has wonderful hands and genuine stopping power, and Browne would no doubt endeavour to slowly wear him down, shuffle him into a corner and bludgeon him out of the contest.

But Parker would likely start favourite given his youth and dynamic speed, which has seen him win 16 of his 18 pro fights by knockout. Browne sports a 24-0 record with 21 wins short of the bell.
