A Tongan family in Sydney is grieving the sudden loss of a beloved mother-of-four, Vaimoana Feohi-Moe-Langi Fonua, who passed away from a heart attack while holding her seriously ill infant son in a hospital.

A Sydney family is mourning the sudden loss of mother-of-four Vaimoana Feohi-Moe-Langi Fonua, who suffered a fatal heart attack while cradling her seriously-ill infant son in hospital.

Vaimoana was comforting her young son, who remains hospitalised, when she suffered a fatal cardiac arrest.

Her passing has sent shockwaves through her family, kāinga (extended family and community), and the broader Tongan diaspora in Australia.

Heartfelt tributes have poured in on social media, reflecting the profound love and respect she inspired.

One grieving family member wrote on Facebook: ā€œWake me up from this bad dream. Tell me it was all a dream a nightmare. Haueee my beautiful big sister Vaimoana Lanivia-Fonua I miss and love you so dearly. God called you home too soon. You left your husband Liongi Jr Fonua heartbroken sis 😭😭😭😭 I do my absolute best for your babies and make sure Mou is okay.ā€

Another close relative shared: ā€œVaimoana Lanivia-Fonua I praise God with all of my heart, for who you are my beautiful sister, I call my day one, my best friend…. Fakafeta’i kia Sihova he ko ia pe Pule ‘o mo’ui [Thank you to Jehovah, for He is the Lord of life]. It truly is an honour to live life with you. I thought we would grow old together, I love you so much. Thank you Vai for being our family’s rock and always putting others before your needs.ā€

Vaimoana is remembered as a selfless caregiver, a pillar of her family, and a devoted friend. Her passing underscores the immense emotional strain faced by families with critically ill children.

A fundraising page has been established to support her husband, Liongi Jr Fonua, and their four children during this profoundly difficult time, particularly to help cover costs associated with both Vaimoana’s passing and their son’s ongoing medical needs.

The family has requested privacy as they navigate this double tragedy.
