We've just demolished an old brick barbecue and propose to bury the
rubble at the bottom of our new (40cm deep) garden bed. Is there likely
to be a problem if I put the mortar in as well as the broken bricks? I
know the mortar is alkaline, but am hoping it'll be deep enough not to
be a problem for me veggies. What do you think?

Unless Newcastle has alkaline soil (which I doubt), I can't imagine that it
would be a problem. Vegies tend to like it a little bit alkaline anyway.
