A national mental health service for young people and their parents say they have experienced a spike in clients accessing LGBTI support services during the highly charged same-sex marriage postal survey period.
ReachOut provides online support for young people and their families across the broad spectrum of mental health needs.
CEO Jono Nicholas said there had been a 20 per cent increase in people accessing LGBTI support services with many contacting them with anxiety over the same-sex marriage survey results.
"We're certainly hearing things around young people saying 'am I a freak', 'will I be accepted?'" Mr Nicholas said.
"It's really the continuous conversation around [whether they will] be accepted, or is this a country where they see a future for themselves?"
"Certainly if you go online and social media you then see some of the more specific, quite awful conversations that can happen through social media and with young people being on social media it's pretty hard to not be exposed to that."
The first batches of same-sex marriage surveys were sent out last week and the No campaign, run by the Coalition for Marriage, officially launched their campaign in Sydney on Saturday night.
"Vote No" was written in the sky over Sydney on Sunday morning with very mixed reactions online showing a divided community.
"One of the things that we certainly want to remind the community is that this group is a very vulnerable group of young people," Mr Nicholas said.
"Having a very respectful conversation and recognising the fact that they are vulnerable means that we need to make sure that they're well supported and they know where to go if they're having a tough time while this debate and survey are occurring."
Mr Nicholas advised parents and young people to make contact through the service, online at ReachOut.com and via the Kids Helpline on 1800 55 1800.
