Tanzid celebrated his magnificent maiden Test century, reaching 100 runs for Bangladesh against Australia. His opening partner, Shanto, also passed 50 for the 16th time in Tests, calmly driving Lyon down the ground for a single.
Bangladesh reached 230-2 in the 64th over, with Tanzid on 100 and Shanto on 50. The tourists have now claimed their fourth consecutive session, leading the hosts with eight first innings wickets remaining.
Australia's bowlers struggled to make an impact on a pitch offering little sideways movement and consistent, slow, loopy bounce. Captain Cummins has kept spells short in the heat and humidity, but the team has created few openings.
