Our Team


Grace City Church is lead by a team of elders. Currently this team is made up of Mike Irving, James Ryburn and Miles Simmonds. 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 where they had been part of Jubilee Community Church for many years. 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 at International Business Systems where he had been running the publishing division worldwide. Mike and Lynn have three children.

James and Heather Ryburn


James has been at Grace City since it kicked off in the early 2000’s.  Having grown up within this church community (aside from a few years serving a church plant in Japan), Grace City is his family in so many ways. James loves meeting new people and helping them connect with the church community. He is passionate about Christians doing life together and among other things helps oversee how people become integrated into church community, City Groups, and Mens and Womens initiatives.

In 2015 James joined the Grace City staff after 12 years working in a variety of project management and business leadership roles. He serves as an elder, an honour and responsibility he does not take lightly.

James and Heather have three young daughters, who they are passionate about seeing grow into all God has called them to be.

Miles and Kate Simmonds


Miles serves as an elder and he has lived in Australia for 10 years and is originally from the UK. Miles met his wife, Kate, in the UK and they both have a passion for worship and lead the church in moving forward in this.


Miles and Kate have a son, Matthew, who is a talented drummer and key part of the youth. Kate also has a gift for teaching and is on the preaching team.


Currently, Miles is an IT Strategy Manager and has worked in Business Intelligence in the past. 


Gillian Markie

Gillian is our senior administrator, having come from a finance background and having a huge heart for the church, she is developing this key role as the church grows. Her organisational skills and her clear foundation of grace are huge assets in this leadership role.

James Ryburn

James loves connecting people together and his heart to see people loved and cared for helps make Grace City a welcoming and embracing family. As well as his connection role, he also oversees our City Groups that are so important in the life of the church.

Kate Kotze

Kate, with her background in teaching, is our children’s pastor. Her heart to see kids grow in God, and develop in Word & Spirit have a huge impact on our children’s ministry. She loves connecting with parents and supporting them in discipling their kids.

Kirsty Eagleton

Kirsty brings her life and fun to the admin team, effortlessly handling the most mundane task while encouraging everyone who contacts the office. There is no doubt that the title we tease her with of ‘chief roster pastor’ is well deserved as she keeps everyone who serves in our many ministries on track.

Lynn Irving

Lynn has a huge heart for discipleship of all types of people, and as well as bringing pastoral wisdom, she also brings a clear encouragement to be the church that brings kingdom advance. This also fits with her wider role alongside Mike to develop leaders in Grace City and related churches and plants.

Matt Irving

Matt assists with our marketing having just qualified as a Graphic Designer. He brings new ideas, freshness and thoughtfulness to all he does. His strongly relational heart and passion for worship and church planting all flow into his work.

Mike Irving

Mike leads the team at Grace City and has a huge heart to see God's Kingdom advancing through the church, believing that the local church, walking in step with the Holy Spirit, is God's answer to see the world changed. Releasing people in their gifting and discipling leaders are key parts of this as well as bringing the reality of grace to the church in Australia and beyond.

Ola Odejayi

Ola is planting a new Grace City Congregation in Sydney’s North West and has a heart for that community to be changed by the Gospel. His strategic Kingdom thinking and gift of communicating Gods Word is already bearing fruit and will continue to take us forward into new areas.
