Australia wrapped up their pre-World Cup Test campaign with a 34-15 win over Samoa in Sydney on Saturday.
A good first-half display, which was rewarded with a 22-3 halftime lead, was offset by an unconvincing second-half performance, with Samoa scoring the first 12 points, before two late tries pushed the home side clear.
Cheika said the game had been a really good hit out for the Wallabies, who now have a 3-2 record this year.
