The problem as I see it, is a lackadaisical approach to writing, regardless or not you went through that poor period of NSW education. Take for example:
Of course it doesn't exclude us, however, it shouldn't mean that each time I come on here I need my English dictionary and thesaurus to keep you lads happy.
The reason you would use a reference like an English dictionary or a "T"hesaurus is because you need to check or double check a word when you are applying yourself to writing something more esoteric than the average vocabulary allows. A post on PPRUNE hardly requires that "each time I come on .....". It is an appalling indictment of English teaching standards in Australia and I guess, of the author's opinion that subject matter is more important than the delivery. It is not.
As for spelling and grammar checkers:
I have a spelling chequer -
It came with my Pea See.
It plane lee marks four my revue
Miss steaks aye can knot sea.
Eye ran this poem threw it,
Your sure reel glad two no.
Its vary polished in it's weigh,
My chequer tolled me sew.
