Does anyone know if these vents are now only on the 230V ovens, which is the standard voltage in Australia? If so then given the 230V model reaches the same temperature as the 120V model then I am curious why the latter does not also have these vents? Perhaps it is a relatively new design change? If so, why were they added, will they be added to the 120V model and why are the vents not shown on any commercial pictures of the oven?
Hi there CanuckNeapoLover and all,
Very happy to hear you got yourself an oven, I really hope you enjoy it and it works well for you!
And yes, the vents you've pointed out behind the handle are on all 230/240V versions of the product but not found on the 110/120V version.
Most components used in the ovens are the same the world-over but there are a few that have slight modifications.
Each region has slightly different safety/compliance requirements that products must meet before being allowed to sell into that area. As a result, depending on the region, there might be some components that are tweaked specifically for that region. This applies to all products.
In this case, the door front panel was updated for 230/240V regions to include these vents which help further cool the metal surface in this area.
If you're interested too, the dials are slightly different between the models also - see if you can pick it

Cheers and good luck with it!
