Thought it would be obvious that coming from outside this zone would be more expensive.....you know as your not in gateshead. In the same way it's a set price in zone A on the metro, however if you come from outside zone A, the price goes up 

Strangers to the area and non bus users, whom this is presumably trying to attract to use the bus rather than simply giving existing passengers a discount, likely won't know where the local authority boundaries lie.
As the fare finder disappeared some time ago, we can't compare any cross LA boundary single/return fares with the new flat fares to see if they jump up as you cross the boundary.
From the map I would think that Newcastle was included in the Gateshead zone (when travelling from Gateshead).
