I got some HIR globes for the high beams off "Max Lumens" on e-bay. Cheap and fit fine after a little trimming of the locating tabs as per
this link. Made a noticable difference.
Be aware though that for my WH Laredo, the owners manual said I had 9005/9006 high/low beams, the globe manufacturers specs listed the WH as having 9005/9006 high/low beams, but my vehicle actually has 9005/H11 high/low beams. Something peculiar to Oz or right hand drive models I guess but I have not been able to find a replacement for the H11s.
The globe mounted actually appears to screw on to the headlight casing so in theory it should be possible to replace the H11 mount with 9006 mounts but I haven't pursued it as they are only low beams after all.
