Leadership Team

It is a real joy to have a dynamic, loving and wholehearted Grace City leadership team that has a massive heart to serve the church. The unity and strength of this team brings great shape to the church and we feel extremely blessed by God for these leaders and others that are being raised up in church life. 


The current team includes: Sandy & Glen, Tania & Steve, Belinda & Wes, Claire & David (not in photo), Matthew, Simon, Teesh & Tom, Kate & Miles, Kate & Quinton, Lynn & Mike



Grace City Church is lead by a team of elders. Currently this team is made up of Mike Irving, Miles Simmonds and Quinton Kotze.

As a team our focus is to see the church grow and mature to see Gospel advance in our neighbourhoods, across our city and through the nations.

Mike and Lynn Irving


Mike and Lynn have lived on the Northern Beaches since 1997, having moved here from Cape Town, South Africa. Mike serves as the lead elder of Grace City Church and has a passion to see the church being the light to Australia that Jesus has called us to be. A key part of this is discipling men & women to grow into all the fullness that Jesus has won for them and releasing them to see the Gospel proclaimed in word and deed throughout the nation. Mike also has a developing apostolic role within Regions Beyond and is part of the Global Team.

Lynn also serves alongside Mike locally and internationally. Lynn also has a heart to see women grow into all God has for them and is passionate about discipling.

Mike has lead in church life for many years while working in a secular job until 2009 when he left his last employment as Vice President of an international IT firm. 


Mike and Lynn are blessed to have 3 incredible adult children and have loved every stage of their growing up, challenges and all!
