Teachers from public and non-government schools met with Premier Dominic Perrottet and Education Minister Sarah Mitchell on Thursday.
It follows a strike by public school teachers and their union last week, the second in less than six months.
The teachers' advisory group came after principals from 10 public schools met with government for the first time last week as part of a separate advisory group to see how their success can be emulated in other schools .
Mr Perrottet said the advisory group would allow teachers to share experiences and identify challenges in the education system that could be improved.
Resourcing issues and administrative tasks that take the focus of teachers away from their classes were two issues the group identified.
The premier said cutting teachers' paperwork, potentially by hiring more administrative staff for schools, could improve learning outcomes for students.
"It needs to be looked at," Mr Perrottet said.
"There is a lot of time taken away from our teaching staff into areas of administration that we should look at."
Ms Mitchell said many of the problems in education were the same in government and private schools.
"Particularly when we look at things like resources around the curriculum, some of the admin around accreditation and registration requirements for teachers, but also around collaboration," she said.
"When you can connect across schools that's when you can share those resources, that information, that mentoring with others teachers in your network, you get really good outcomes."
Mentoring, guiding documents and sharing of expertise would be the main resources that could be shared by public and private schools, rather than school infrastructure.
Teachers on the advisory group were drawn from four public schools and six private schools.
Opposition education spokeswoman Prue Car accused the government of being out of ideas to fix the state's education system and the looming teacher shortage.
She said the government should sit down with the teachers union to work through their concerns instead of holding roundtables and advisory groups.
"Dominic Perrottet, we know, loves the sound of his own voice but another talkfest is not going to recruit one single teacher," Ms Car said.
Labor has resisted coming out with a specific policy to lift teacher wages and ease their workloads, however Ms Car said teachers should be paid more.
"Teachers are simply not paid enough, there's not enough of them coming into classrooms and they're not valued enough," she said.
Ms Mitchell said she plans to meet with the Teachers Federation as the government looks to reach a new industrial agreement with the state's teachers.
"I meet with the federation regularly, I meet with the principals group regularly and I will continue to do that," she said.
