However, loving family photos documenting trips to the zoo and the local golf course painted a very different picture to the messages shared on Facebook.
Ms Bond was a well known golfer in her local community and worked at Kooindah Waters Golf Club as a golf shop and drinks cart assistant.
"An extremely good golfer, her handicap fluctuates between 4-7 and she is the current ladies club champion," the club's website states.
"Erica's outgoing personality will ensure all your golfing needs are catered for and if on the golf course she will ensure you will not go hungry or thirsty."
Officers from Tuggerah Lakes established a crime scene and detectives were investigating.
Police could not comment on the cause of death but did confirm officers were not looking for any other people relating to the incident.
Neighbours reportedly heard a woman's cries for help yesterday and one told The Daily Telegraph the family kept to themselves.
"I've heard them have a few fights occasionally but nothing serious, I didn't think," the unnamed neighbour said.
Tuggerah Lakes police command acting inspector Matt Kelly confirmed to the Central Coast Gosford Express Advocatethe two deaths were a murder-suicide.
Lachlan was a pupil at Tuggerawong Public School and its principal Grant McFarland wrote a message in response to the deaths on social media overnight.
"By now many of you would have heard that one of our students and parent has passed away," he wrote on the school's Facebook page.
"I wanted to confirm that the school will be open tomorrow (today) and that we are ensuring that significant additional support is available for any student who may need it tomorrow and over the coming days.
"It is your personal decision about what sensitive discussions you may choose to have with your children tonight. The school will have a carefully planned approach to supporting all students tomorrow and moving forward.
"The staff and I appreciate the tremendous support of our parents and our broader school community at this challenging time. Our heartfelt thoughts are with our much valued student's family and friends at this time."
Tributes from heartbroken parents were then posted on the school's Facebook page.
"So very sad. My daughter is heartbroken," wrote one parent.
"Lots of love and support to all our beautiful teachers during this very sensitive and hard time."
"My thoughts are with everyone, the family, our gorgeous children, our amazing teachers, aides and office staff, and our beautiful parents at this very emotional time," wrote another. "Our community is strong. Together we can all get through this."
NSW Police said the investigation was in its early stages and a report was being prepared for the coroner.
