I'm suspecting this is a propaganda photograph?

It definitely shows a scene from a peaceful and friendly occupation. I think almost all of the Bain war photos are propaganda, depending on which side the audience for the photo was rooting.

I wonder if the guy on the bike is making some sort of rude gesture (early photo bomb). The only thing I can think of is the "biting the thumb" gesture that means screw you. He looks too intently at the camera not to be in some way making his own comment on the scene.

looking at the hi-res version, it seems he has a pipe in his mouth.

Castlemaine Perkins is a brewery at 185 Milton Road, Milton, Brisbane, Queensland, Australia. It is a wholly-owned entity of the Japanese-controlled Lion company. Operations began in 1878 and continue today. Castlemaine Perkins is the home of the XXXX beer brand. In 1877, brothers Nicholas Fitzgerald and Edward Fitzgerald partnered with a Brisbane commercial firm to buy the site of a failing distillery and establish a brewery, named for the Fitzgeralds' existing Castlemaine Brewery.[1] They began to brew beer there in the following year and the brewery continues production to this day. The first beverage was called XXX Sparkling Ale.[2] In 1866, Patrick Perkins started the Perkins Brewery in Toowoomba. In 1872, he later extended his operations to Brisbane with the purchase of the City Brewery in 1872.[3] The company restricted its operations entirely to brewing by 1916.[4] XXXX was introduced with a new advertising campaign in 1924 after the brewery employed German brewer, Alois William Leitner.[2] The advertising included a depiction of a little man wearing a suit with a smile, a wink, and a boater hat. The so-called 'Forex Man' soon became one of the most recognized symbols in Queensland.[2] In 1928 (long after the death of Patrick Perkins in 1901), the Perkins brewing company was bought by the Castlemaine Brewery with the new company being known as Castlemaine Perkins Limited.[3] In March 1980, Castlemaine Perkins merged with Tooheys to form Castlemaine Tooheys.[5] Bond Corporation purchased Castlemaine Tooheys in 1985.[6] Castlemaine Tooheys was acquired in 1992 by Lion Nathan.
