1. Vaccination is the best way to protect children from serious disease, especially those who are too young to be vaccinated, or those who can't be vaccinated because of medical conditions.

2. Requiring parents or guardians to provide documents at enrolment will help lift population vaccination coverage rates and complement other public health activities to control serious vaccine preventable diseases. Most of these diseases historically have infected children at a higher rate because of lack of immunity.

3. In 2011 and 2012 NSW experienced measles outbreaks that were prolonged due to people having missed vaccinations in childhood, or being late with vaccinations. The more people who have their children vaccinated on time, the greater the ability to control serious vaccine preventable disease outbreaks. While around 90% of children at 1 and 2 years of age in NSW are fully immunised, at least 95% coverage is needed for effective disease control.

4. Unimmunised children who due to medical reasons or whose parents or guardians have a conscientious or religious objection to immunisation will still be able to attend childcare provided that the appropriate documentation has been provided. Children who are behind with their immunisation schedule will also be able to access child care once the appropriate documentation has been provided that shows they have either caught up or are on a recognised catch-up schedule.

1. Unvaccinated children may still be asked to stay at home if there is an outbreak of a vaccine preventable disease in a childcare centre.

2. Overseas immunisation records will not be accepted. Children who were vaccinated overseas will need to have their immunisation records assessed by an immunisation provider who will transfer the information to the ACIR. A revised Immunisation History Statement will then be issued to parents/guardians.

3. Childcare centres will now bare the cost of ensuring that documents are stored in a securely for up to three years and they then risk fines of up to $4,000 if inspectors discover children in their care who don't have proof of vaccination or exemption.

4. The exemption where a parent or guardian "has a conscientious objection, including religious beliefs, to vaccination" provides a very broad scope for avoidance of vaccination despite the legislation and has the potential to reduce the effectiveness of the amendment.

5. Some sections of the community have expressed the view that this requirement impinges on a parent or child's civil rights.
