I think it does, based mainly on the number of ALR-67 sets included in sales notifications that include EA-18Gs.
The RAAF order for 12 FA-18E and 12 EA-18G includes 24 ALR-67. That's one per aircraft.

The Finnish order for 50 FA-18E, 8 FA-18F and 14 EA-18G includes 65 ALR-67. That suggests one per E and G and one spare. It also suggests that the Finnish Fs are not fully combat capable.

The RAAF order for 12 FA-18E
I thought that the RAAF ordered F/A-18Fs not F/A-18Es?
For the EA-18G, which has the ALQ-218 receiver, does the value of retaining the ALR-67 RWR lie in giving the EA-18G quicker but less precise threat warnings?
