Two Sussex teams stacked with international experience proved too strong for both the women's and men's Aboriginal squads in Hove with comfortable victories in both matches on Friday.
The loss for the Aboriginal men was their first on tour, ending a three-game winning streak as Dan Christian's side fell 99 runs short of the hosts' 5-188.
In the women's fixture, Sussex won the toss and sent the Aboriginal XI into bat and immediately set about building an intimidating total.
Paige Schofield (58) and Fran Wilson (53) smashed a 111-run partnership off 70 balls helping their side to 4-182 off their allocated overs.
In reply, disaster struck early for the Aboriginal XI with key trio Ashleigh Gardner (0), Emma Manix-Geeves (1) and Hannah Darlington (4) all falling cheaply in the first three overs.
Despite some solid performances in the middle overs from Christina Coulson (33) and Roxanne van Veen (31), chasing down the huge total proved too much and the Aboriginal XI finished their 20 overs 79 runs short on 8-103.
In the men's match, first-class pacemen Scott Boland and Brendan Doggett struck early claiming the wickets of Philip Salt and Luke Wright respectively to leave Sussex 2-12.
Laurie Evans and Tom Bruce steadied the ship before Ben Patterson claimed the wicket of Bruce. Patterson followed up later clean bowling Evans for 44 before Michael Burgess and David Wiese put on a clinic to close out the innings for Sussex.
Burgess was dismissed for 44 off just 21 balls and Wiese remained undefeated just short of a half century on 49 off 21 balls.
The Aboriginal XI struggled to find rhythm with the bat as the star-studded Sussex bowling line up of Hobart Hurricanes star Jofra Archer, England limited-overs quick Chris Jordan and fellow internationals Danny Briggs and David Wiese took wickets at regular intervals.
Only the skipper Christian (24) and Rex Strickland (21) troubled the scoreboard as the visitors lowered their colours for the first time on tour with a comprehensive defeat.
The historic tour resumes on Sunday when the women take on the National Cricket Conference and the men face off against Derbyshire at Derby's County Ground.
