As show bosses confirmed last month, disaster strikes as the couple's wedding marquee blows up in one of 2013's biggest storylines.
Fans can expect a beautiful ceremony for Toadie (Ryan Moloney) and Sonya (Eve Morey) as they tie the knot surrounded by friends and family.
However, when a gas bottle suddenly explodes, the marquee collapses - trapping some of the guests inside.
Neighbours chiefs have confirmed that two characters will be killed off in the storyline, which airs on screen next week in Australia and in the week commencing Monday, April 15 on Channel 5 in the UK.
Below, Digital Spy takes a behind-the-scenes look at the filming of the episodes.
