Java Sea. c. 1942. A Japanese bomb, often referred to as an "egg" exploding astern of the cruiser, HMAS Hobart.
If it is Java SEa in 1942, it should be before Coral Sea. Isn't it a quad Bofors in foreground?
Anyway there is something to correct...
HMAS Canberra:

c. August 1942. Anti aircraft gun crews wearing flash protection clothing on the starboard side of HMAS Canberra looking out for high level bombers. In the foreground is an S1 mounting with its twin 4 inch Mk XVI high angle gun. The barrels of the S2 mounting are in the background (left) and a 20mm Oerlikon anti-aircraft gun (centre) points skywards. To its left is a Vickers machine gun mounted on a tripod anti-aircraft mounting. Note the splinter protection around the superstructure (top right).

Two 4 inch anti-aircraft guns situated amidships on both sides of the Kent class cruiser HMAS Canberra which was in RAN service from 1928 to 1942. An additional four guns of this type were added to the armament after the outbreak of the Second World War. HMAS Canberra was sunk off Savo Island on 9 August 1942 in the battle for Guadalcanal.
I don't believe that "additional four guns of this type were added to the armament after the outbreak of the Second World War" and that later 4 twins were fitted.
I mailed Ahoy Mac, owner of a website and officer of Canberra during the Savo Island battle. He told me that Canberra had 4 single 4" and 4 single 2 pdr and 2 quad 0.5" MG.
Australia had 2 octuple 2 pdr and Hobart no 2 pdr.
If Canberra had only 4 4" and 4 2 pdr. she was the least armed of all british heavy cruisers in terms of AA guns.
