Thanks so much Alex and Nicole for dropping by. I’ve worked with Alex on Playschool and met Nic when they were shooting the pilot for Home and Away and I was on A Country Practice, and they are such great people.
'A great surprise for Ray and the crew too. And a personal shout out to the luminous @justineclarke_who first brought Roo to life and the fans for constantly supporting our show.'
Esther Anderson wrote a touching tribute to Instagram, along with a large gallery of throwback photos.
She gushed: 'Congrats @homeandaway on 30 wonderful years!!!!! Some of my fondest memories and favourite friendships were made on this show!! What an honour to have been a part of it, cheers to you, all the cast and crew, past and present and all the wonderful fans!!!! Enjoy the celebration.'
Dannii Minogue was another who lovingly celebrated the iconic soap opera.
Posting a hilarious throwback video of a scene from the show, she wrote: 'Summer Bay >>> service with a smile 😃 #moremilk 🥛'
Dannii posted another video, this time her character strolls the beach in a white bikini.
Steve Pennells, Channel Seven's Sunday Night reporter, also took to social media to share some behind-the-scenes snaps while filming the 30th anniversary segment.
He wrote: 'Prepare for a beautiful little moment in Australian tv history. I’ve secretly reunited Home and Away’s original golden couple - Nicolle Dickson and Alex Papps - and together we snuck on to the Home and Away set to surprise show legend Ray Meagher.
'How did he react after all these years? It’s pretty special. Find out tonight when “Endless Summer - 30 Years of Home and Away” airs in Australia and the UK.'
