The MCG will host stand-alone finals for the men's and women's World Twenty20s after Cricket Australia promised to give both tournaments equal billing.
Ten countries will compete in the women's T20 in February and March of 2020, before 16 men's teams arrive for their tournament in October and November of that year.
Both semi-finals for the women's tournament will be held in Sydney, while the men's will be split between the SCG and Adelaide Oval before both culminate in the 100,000-seat MCG.
The tournament will mark the first time the men's and women's competitions have been split when both played in the same year.
It comes after 24,000 people crammed into a sold-out Lord's in London last July for the final of the women's 50-over World Cup.
"Australia is a sporting nation, with diverse and passionate fans who love cricket," organising committee chief executive Nick Hockey said.
"We've designed ICC World T20, comprising stand-alone women's and men's events, to be more inclusive, more accessible and more connected than ever before, so that everyone can join in."
Eight cities in total will be used between the two tournaments, with Hobart and Geelong to feature in the men's group stage while Canberra, the WACA, Junction Oval in Melbourne and Spotless Stadium to each host women's group matches.
Australia's six main venues - including Perth's new Optus Stadium and the Bellerive Oval in Hobart - will then be used for the Super 12 stage of the men's tournament.
It was another strange day for the Black Caps involved in yesterday's Indian Premier League auction, with several of New Zealand's key players going unsold.
After the likes of Kane Williamson and Brendon McCullum secured big money deals on the first day of the auction, the remainder of the Kiwi contingent were hopeful of earning similar stints playing in the IPL.
All-rounder Corey Anderson was the first name out of the hat for the Kiwis, although none of the eight franchises were interested in his services.
However, things fared much better for seamer Trent Boult, selling to the Delhi Daredevils for $468,000 where he'll join international teammate Colin Munro.
Mitchell Santner would also snare himself a contract, picked up by Stephen Fleming's Chennai Super Kings for his reserve price of $107,000.
After going unsold on the opening day, Tim Southee was one of the final players picked up, moving to Daniel Vettori's Royal Challengers Bangalore for his $214,000 base price.
Ultimately though, it would be a dire night for the Black Caps, with many going unsold on the same night as surrendering the three match Twenty20 International series to Pakistan in Tauranga.
There was no interest for spinner Ish Sodhi, who was unsold on the auction's opening day despite being the world's top ranked T20 bowler.
Opener Martin Guptill was another unsold star, even though teams had expressed an interest to see him included in the auction's second day.
Mitchell McClenaghan was another surprise omission, having finished fourth on the tournament's overall wicket takers list in 2017, and having no international commitments after turning down a New Zealand central contract.
The likes of Matt Henry, Adam Milne and Lockie Ferguson were the other stars who failed to find a buyer after competing in last year's edition.
