We see and understand things not as they are, but as we are." Explain how cultural differences impact on perception

If the values are accepted and bought into by everyone in the organisation then people's behaviour will reflect those values. The aggregated behaviour then becomes the prevailing culture of the organisation.
A disconnect happens when an organisation publishes its values such as "we work as one team" and rogue elements in the organisation decide that they don't play by those rules. Very common I'm afraid.

Something to help with your understanding of the answer and the question itself:

The built environment provides the setting and backdrop by which we live our lives, and
impacts on our senses, our emotions, participation in physical activity and community life,
our sense of community, and general wellbeing. Meanings are generated by buildings and
spaces, which we 'read' as we pass through them. Places are created and shaped by those in
control of resources and with certain interests, which affects our degree of access to, and the
way we use, those spaces.
People living in particular localities may be prone to particular diseases if the aetiology of
that disease is located in the environments in which they live. Although disease and illness
may be caused by a virus or toxic substance, it may be social institutions and practices which
actually create the circumstances in which people come into contact with these disease-
inducing agents. Places have certain environmental characteristics, such as the availability of
healthy foods, health-affirming services, community norms and so on, which influence health
behaviour. Health disadvantage is exacerbated in socially and economically disadvantaged
settings. Health promotion strategies need to take into consideration the impact of social
structure, place and time on people's health-related knowledge, attitudes and behaviours.
People with disabilities are not only marginalised by social and political structures, but these
same structures are reflected in the built environment. These built forms serve to reinforce
the physical and psychosocial isolation associated with their disability.

Understanding of cultural differences is extremely important for business people. People from different cultures perceive things in numerous ways. When selling products and connecting with clients, owners want to ensure that they are within cultural boundaries.

Definition of many words have changed over last 100 years, Webster Dictionary (used world wide since late 1800'S) has defined many terms, words, and phrases in a way that has been widely adapted in many nationalities, and popularized in to what we know today as real world speech. Modern day generation, (born 80s to 2017) have introduced a stylish way of redefining uses and meanings of everyday words. Slang pronunciation pertaining to a certain crowd, gang, group, clan, clik, sect, nationality, etc. have also achieved their personal meaning in speech dialect, All is American Slang, criminal slang, back slang, rhyming slang, and other types of slang. Purposefull strong directive words used singularly or/and spoken combined in a certain order/phrase and/or certain tone of voice, mentioned and misused around and within the Not Agreeable crowd will cercaintly have a negative backfire.

Being aware of what the word means literally, what it implies, and in what context it is applied. Although 90% of communication is non-verbal, just nuances of language can lead to miscommunication. Just what is considered appropriate speech may also require sensitivity to a cultural norm.

The country has maintained its ties with the U. K..and monarchy. aIndeed, their prime minister can be dismissed via this link. Historically, it was settled largely by the English. Their government is based on the parlimentary model. Bear in mind that Australia is a relatively new country although an ancient continent with a native population having lived there about 60 thousand years. Part of the population would like Australia to be a Republic, the other part would like it to remain tied to the U. K. Although there is definitely an Australian culture, it is closer to British culture than U. S. culture. It does have some world class universities. One PM could speak Mandarin Chinese but was clearly Anglo. There is a tradition of giving people a fair go although there is more friction arising from conflicting ideas about settlement of refugees from the Middle East. Thus far, they are content to make use of talent where they find it and that includes the population from the U. K..although there are colorful names attached to this segment. You certainly see more British TV in Australia than you are ever exposed to in the U. S.. There is no restriction regarding country of origin for the PM's office, unlike the U. S. presidency.
