Candidate passages:
Australia’s intelligence and security agencies maintain close working relationships with the foreign and domestic intelligence and security agencies of other nations.
As of 22 October 2008, ASIO has established liaison relationships with 311 authorities in 120 countries. 
The people of the island complex that includes Malaysia, Indonesia and the Philippines are ethnically similar, with most speaking closely related Malayo-Polynesian languages.
Both countries also have large Chinese minorities, who often maintain close cross-border ties. 
Filipinos in Indonesia generally maintain good interethnic relations with their Indonesian neighbours, with whom they feel culturally closer than Europeans or Americans; Indonesians stereotype Filipinos as being gregarious and cheerful.
However, there are fears that Filipinos in Indonesia may become the targets of kidnappings by local militant groups such as Jemaah Islamiyah in an attempt to secure the release of JI members imprisoned in Philippine jails. 
Dunbar's number is a suggested cognitive limit to the number of people with whom one can maintain stable social relationships.
These are relationships in which an individual knows who each person is and how each person relates to every other person.
This number was first proposed by British anthropologist Robin Dunbar, who found a correlation between primate brain size and average social group size.
By using the average human brain size and extrapolating from the results of primates, he proposed that humans can only comfortably maintain 150 stable relationships.
Proponents assert that numbers larger than this generally require more restrictive rules, laws, and enforced norms to maintain a stable, cohesive group.
It has been proposed to lie between 100 and 230, with a commonly used value of 150.
Dunbar's number states the number of people one knows and keeps social contact with, and it does not include the number of people known personally with a ceased social relationship, nor people just generally known with a lack of persistent social relationship, a number which might be much higher and likely depends on long-term memory size.
Dunbar theorized that "this limit is a direct function of relative neocortex size, and that this in turn limits group size ... the limit imposed by neocortical processing capacity is simply on the number of individuals with whom a stable inter-personal relationship can be maintained."
On the periphery, the number also includes past colleagues, such as high school friends, with whom a person would want to reacquaint themself if they met again.
