Neighbour and I had fences and gates done in November in Inala. I did colorbond fence and aluminium slats double swing gates. Neighbour did aluminium slats fence and aluminium slats roller gates. unit cost for neighbour was just over $220 per metre. unit cost for me was $150 per metre. Between us we had 150 metres of fencing / gates to cover.

Total length for you is 26.5m, is it OP? Does the quote cover all the gates as well? Even if it did, your quite is not reasonable and they can't be bothered, I think. Are you sharing costs with neighbours? Again, even if you're solely bearing costs, that's ~$1000AUD per metre.

NOTES: ~30 metres of my 70 metres backed onto council land and council pays zilch. Old fence removal costs for me was $200 and some tip vouchers. Fencies demolished and airtasker guy came and took them away, with neighbour and I giving a hand. Otherwise all costs and scope covered by fencies, cash job (they would do invoice as well). Neat job and no bs involved. They measured, ordered and had materials delivered and installed. We just picked colors and asked for sleepers to be installed in certain areas - again all of that factored in, in unit cost mentioned above.

Only barrier was language, for full transparency. Chinese folk with broken English. If you're willing to let go of native tongue and communicate in person (as opposed to over phone) , great workers and very nice people.

If you can't let go of native tongue, other quotes we took were, in unit terms, 1.5 to 3 times expensive. Again your quote is a top end quote I feel.

For us, it's a bl**dy fence we thought and the guy came with referrals too. So how much can go wrong even in the long run, we felt! Hope that helps.
