That is unfortunately true... Toyworld and Mr Toys Toyworld are essentially two different entities with different supply chains, so something new or different appearing at one, may not show up at the other if limited stock arrived into the country or it is old stock being discounted to one retailer that wanted it. It can also mean arrival times being completely different for new product lines.

Just like Sydney, Brisbane doesn't really have any "Toyworld" stores that aren't Mr Toys Toyworlds, so if something gets sighted in Melbourne Toyworlds (which is where their main warehouse is located), Sydney and Brisbane can end up missing out, or have to wait for another retailer to get them in.
