    COVID-19 update

    Update 18/10/2021

    Wellington Street Psychology has updated its COVID safe policy to include that all clients attending in-person appointments are required to be fully vaccinated with an approved COVID-19 vaccination (i.e., have received their second dose). Telehealth remains the available alternative where this is not possible. This is for the safety of our staff, clients, and community.

    Given the current community health concerns we ask all those who visit our clinic to follow these guidelines:

    1. If you have any symptoms consistent with COVID-19, or any flu-like symptoms, please do not attend your appointment in person. Please contact your treating psychologist as soon as possible and they will organise to meet via TeleHealth;

    2. Please ensure you wash and sanitize your hands when entering the premises – hand wash, hand sanitizer, and disposable paper towel are available in the common areas of the practice;

    3. Please wear a mask, fitted appropriately, at all times;
    4. We ask that any friends or family members who may support you to get to your appointment not enter the premises (unless you are under 18 years of age). If you do require a friend or family member to wait with you please let your treating psychologist know prior to the appointment;

    5. Please maintain a 1.5 metre distance from all others in the waiting room (the waiting room is currently configured to support this so please take a seat in the allocated chair positions);

    6. Please check in in via our QR code when you arrive. If you are not able to use the QR code, please let reception or your clinician know and they can support you to sign in manually;

    7. TeleHealth appointments are available and your treating psychologist will discuss this option with you directly.

    Our practice receives regular professional cleaning and we will continue to prioritise your health and safety.

    Wellington Street Psychology respectfully acknowledges the Yaluk-ut Weelam Clan of the Boon Wurrung peoples.
    We pay our respects to their past, present, and emerging Elders, and uphold their continuing relationship to this land, the land on which Wellington Street Psychology stands.
