This is the tear-jerking moment a toddler was reunited with her teenage brother after he saved her from drowning.

Eric Johnson, who was 18 at the time, saved his little sister by performing CPR after he found her floating in the family's swimming pool.

Rose Johnson, who was two at the time, was at home with her brother and mum Nina Johnson, 43.

Nina and Rose both exited the living room for a few minutes and Rose took this opportunity to escape into the family backyard.

When Eric returned, he noticed that the door was opened and ran to the swimming pool.

The 18-year-old found his little sister unconscious in the pool.

He pulled her out immediately and performed CPR.

A few moments later mum Nina rushed out and called emergency services, but by the time she did the little girl was already regaining consciousness.

First responders arrived shortly after and rushed the two-year-old to hospital and put on a ventilator for two days.
