Every year over 30,000 Australians die from sudden cardiac arrest. Without a defibrillator nearby and applied to them within 3-4 minutes, they didn't really have a chance.

Together, we can change that.

  • Every minute matters

    For every minute that defibrillation is delayed, someone's chance of survival decreases by 10%.¹

  • Critical to survival

    Less than 5% of sudden cardiac arrest victims survive without immediate CPR or defibrillation.²

  • Defibs make the difference

    Survival increases by up to 70% if a defibrillator is on hand.³

61% of employees say their workplace either doesn't have a defib or they don't know where it's kept. The need for more workplaces to be equipped with a defibrillator is clear. Here's your chance to make a difference.
