Bumrah, easily the visitors' star man so far in the series, said it was difficult for the players to come out to Australia and play in such different conditions from what they are used to.
The 35-year-old Boland will play his first Test since last year's Ashes in England when he fronts up for the pink ball match at the Adelaide Oval starting on Friday.
At the break on day four, Australia were 104-5 with a defiant Travis Head not out 63 and Mitchell Marsh on five as they chase a near insurmountable 534 to win.
